This page covers biological details of component Broca's Area Pars Triangularis. Region is part of aHuman target integrated biological model.

• Top-down path to region: Cerebral Cortex -> Anterior Lobe (NC.LOBE.ANT) -> Prefrontal Cortex (NC.AL.PFC) -> Lateral Prefrontal Cortex (NC.AL.LPFC) -> Ventrolateral Prefrontal Cortex (NC.AL.VLPFC) -> Broca's Area (NPE.NC.PFC.BRA) -> Broca's Area Pars Triangularis (NPE.NC.BRA.PT) (see Mind Maps)
• Type: cortex
• Brain area: Neocortical Brain - Unimodal Execution Area
• Brodmann ID: 45
• Role: cortex.generic
• Function: Language production and prefrontal associational integration, propositional language comprehension
• Notes to function: Triangular Inferior Frontal Gyrus, switching between semantic sub-categories in word retrieval
